In an interview during the 40-hour standoff in Portland, Luke Strandquist describes what it’s like on the front line of standing up to Shell Oil.

Cloaked in early morning darkness, 13 Greenpeace volunteers climbed over the edge of the St. Johns Bridge in Portland, Ore. on Wednesday and rappelled down climbing ropes so they could hover 100 feet above the Willamette River. Their goal: blocking a Royal Dutch Shell ship en route to support the company’s drilling in the Arctic.

Hundreds of corporate giants have rallied to urge governors to see the upcoming regulations as a boost for the economy.

Three hundred sixty-five companies and investors sent letters on Friday to more than two dozen governors supporting the Environmental Protection Agency's plans to significantly reduce carbon emissions from power plants, urging even the most recalcitrant states to recognize the economic and environmental benefits of the new rules.

The Texas Public Policy Foundation is proposing an interstate compact to defy federal law and "shield" states from the EPA's imminent Clean Power Plan.

With the Obama administration poised to issue its sweeping rules to cut carbon pollution from power plants, a Texas-based conservative think tank is making a far-fetched bid to quash the new regulations.

Records of the flowering of plants, the arrival of migrating birds, and the onset of frog mating calls show spring is arriving as much as 14 days sooner.

If actions do indeed speak louder than words, plants and animals are telling us in no uncertain terms that human-caused climate change is changing their lives—with potentially dire consequences for the ecosystem.

With households and large companies turning to solar, SolarCity moves to make its power accessible for the smaller commercial market.

In a move to accelerate the spread of solar power in the United States, the nation's largest residential solar installer launched a new offering Tuesday aimed at the underserved small- and medium-sized business market.

SolarCity has grown quickly with a boost from new financing options for residential installations that have removed or significantly lowered the up-front costs. Now the company hopes to do the same thing for smaller commercial customers.

Groups opposed to the $5 million ExxonMobil settlement are worried that drinking water for 750,000 Arkansas residents isn't protected.

ExxonMobil's $5 million settlement for polluting water during the Pegasus oil pipeline spill may be final as soon as this week. But many Arkansas water agencies and cities are blasting the penalty and other requirements in the pact as being too weak and too reliant on struggling federal pipeline regulators to keep the 1940s-era pipeline from failing again.

Clinton's platform on climate and energy made headlines this weekend, but it did not break much new ground.

With solar power and wind electricity booming, Hillary Clinton promises to double down on them if she is elected president.

With polls indicating swing state voters believe human activities are causing climate change by a 2-1 margin, her new platform on climate change mocks Republican right-wingers as being out of touch with reality.

With just five months until Paris, document manages to clarify guiding principles, but the most critical issues are still far from resolved.

If diplomacy is the art of keeping one's options open, then the negotiators of a new Paris climate change treaty must be consummate diplomats.

And if using brackets in a draft text is the equivalent of a diplomatic emoticon—one that signals [uncertainty] [dispute] [intransigence]— then the talks must have gone into a peculiar form of emoji overdrive.

Put forth by the co-chairs of the Paris process on Friday, a new 83-page treaty draft remains a tangle of bewildering brackets sandwiched among opaque options highlighting areas of disagreement.

One in six wells were fracked less than one mile below the surface, at the same depth of known water sources, according to a new study.

The nation's first survey of fracking well depths shows shallow fracking is more widespread than previously thought, occurring at 16 percent of publicly recorded sites in 27 states, posing a potential threat to underground sources of drinking water.

The Kalamazoo River near Marshall, Mich. today teems with kayakers paddling amid swimming turtles, buzzing dragonflies and fish that leap from the water—with few visible scars of the environmental disaster that struck the riverside community five years ago.
